Frontier Airlines launched nonstop service between Boise Airport (BOI) and Harry Reid International Airport in Las Vegas (LAS) on September 10, 2026. The route operates four times per week aboard Airbus A320neo aircraft, with introductory one-way fares from $59, per the Frontier Airlines press release.
The service is Frontier's second route from Boise, complementing the Denver route the ultra-low-cost carrier launched in 2025 when it re-entered the Idaho market. The Boise–Las Vegas launch gives travelers a third nonstop carrier on the corridor, alongside Alaska Airlines and Southwest Airlines, which already serve the market.
The route is part of a nine-route expansion Frontier announced between September 2026 and January 2027, seven of them domestic and two international. Most of the new services fill gaps left by Spirit Airlines following that carrier's market exit, per InsideFlyer. Three routes in the batch are seasonal, operating only through early January 2027.
Frontier's $59 promotional fare was valid for travel October 1 through November 19, 2026, with a 21-day advance purchase requirement. The airline also rolled out its "New Frontier" product refresh alongside this expansion, including UpFront Plus seating with extra legroom and a guaranteed empty middle seat, and a new First Class cabin.
Aviation Week confirmed the route launch in its September 14 rolling industry update.
